I am working on a scoring model using a logistic regression. Since my 
sample is very imbalanced (+/-2000 negatives vs. +/-150 positives) I was 
thinking of bootstrapping the results. 

However, I dont know how to resample balanced sets - I think that not 
specifying balanced sets decision rules can result in large type 1/2 
errors. 

Any comments on this?

Thank you very much in advance!
